So then you don't believe in the communion of saints espoused in the Apostle's Creed or do you simply see this communion as in this world?
A “saint” in this regard is likely being seen as a memeber of the faith, just as “catholic church” is simply the long hand for the church.
Please do note that it is lower cased. Also note this is (to my understanding) not used by most Protestant denomonations.
The second. As I’ve been saying, we are saints, prophets and kings, through Christ. When I have fellow Christians praying for me, it is a communion of saints.
